The modified lines should be:

    my $image = GD::Image->new($width, $height, $self->gd->truecolor )
+; 
    $image->transparent( $self->gd->transparent() );

Still essentially untested. I haven't found an image with a transparent background kicking around.

It runs with the gd, but transparent() returns "255" for gif and "-1" for png. The result is black background for both. I think I'll just go with ImageMagick and resize to png since that gives me a real alpha channel and not just a single color transparency, as a result i get smooth edges.

Thanks a lot for your help.

Thanks a lot for your help

But in the interests of finding a fix for Image::Resize, could you post one of your images with a transparent background on ImageBin for me to play with?
